  • Visually-guided robot navigation: from artificial to natural landmarks 

    Celaya Llover, Enric; Albarral Garcia, Jose Luis; Jimenez Schlegl, Pablo; Torras, Carme (2007)
    Conference report
    Open Access
    Landmark-based navigation in unknown unstructured environments is far from solved. The bottleneck nowadays seems to be the fast detection of reliable visual references in the image stream as the robot moves. In our research, ...
  • Direct position analysis of a large family of spherical and planar parallel manipulators with four loops 

    Borràs Sol, Júlia; Di Gregorio, Raffaele (2008)
    Conference report
    Open Access
    The direct position analysis (DPA) of a manipulator is the computation of the end-effector poses (positions and orientations) compatible with assigned values of the actuated-joint variables. Assigning the actuated-joint ...
  • Natural landmark detection for visually-guided robot navigation 

    Celaya Llover, Enric; Albarral Garcia, Jose Luis; Jimenez Schlegl, Pablo; Torras, Carme (2007)
    Conference report
    Open Access
    The main difficulty to attain fully autonomous robot navigation outdoors is the fast detection of reliable visual references, and their subsequent characterization as landmarks for immediate and unambiguous recognition. ...
  • Outdoor delayed-state visually augmented odometry 

    Illa, Viorela Simona; Andrade-Cetto, Juan; Sanfeliu Cortés, Alberto (IFAC, 2007)
    Conference report
    Open Access
    This paper presents an efficient approach to outdoor visually augmented odometry. The technique computes relative pose constraints via a robust least squares minimisation of 3D point correspondences, which are in turn ...
  • Vision-based loop closing for delayed state robot mapping 

    Illa, Viorela Simona; Andrade-Cetto, Juan; Valencia Carreño, Rafael; Sanfeliu Cortés, Alberto (2007)
    Conference report
    Open Access
    This paper shows results on outdoor vision-based loop closing for Simultaneous Localization and Mapping. Our experiments show that for loops of over 50m, the pose estimates maintained with a Delayed-State Extended Information ...
  • Dynamic equations of motion for a 3-bar tensegrity based mobile robot 

    Mirats Tur, Josep Maria; Hernández Juan, Sergi; Graells Rovira, Albert (2007)
    Conference report
    Open Access
    Tensegrity structures can give a new approach to the construction of mobile robots with different shapes and properties that usual robots, wheeled or legged, do not have. Tensegrity are light, deformable structures that ...
  • Outdoor landmark-view recognition based on bipartite-graph matching and logistic regression 

    Todt, Eduardo; Torras, Carme (Institute of Electrical and Electronics Engineers (IEEE), 2007)
    Conference report
    Open Access
    This paper describes the extraction of visual landmarks from outdoor images for mobile robot applications. The concept of group of landmarks, called landmark-view, is introduced, aggregating the most relevant landmarks ...
  • Exploiting single-cycle symmetries in branch-and-prune algorithms 

    Ruiz de Angulo García, Vicente; Torras, Carme (2007)
    Conference report
    Open Access
    As a first attempt to exploit symmetries in continuous constraint problems, we focus on permutations of the variables consisting of one single cycle. We propose a procedure that takes advantage of these symmetries by ...
  • Human motion prediction via spatio-temporal inpainting 

    Hernández Ruiz, Alejandro José; Gall, Juergen; Moreno-Noguer, Francesc (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    We propose a Generative Adversarial Network (GAN) to forecast 3D human motion given a sequence of past 3D skeleton poses. While recent GANs have shown promising results, they can only forecast plausible motion over relatively ...
  • Observer design for Takagi-Sugeno Lipschitz systems affected by disturbances using quadratic boundedness 

    Yang, Ruicong; Rotondo, Damiano; Puig Cayuela, Vicenç (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    In this paper, a proportional observer design using quadratic boundedness is proposed in order to estimate the state of a system described by a Takagi-Sugeno model with a Lipschitz nonlinearity term, and affected by unknown ...
  • Seeing and hearing egocentric actions: how much can we learn? 

    Cartas Ayala, Alejandro; Luque, Jordi; Radeva, Petia; Segura, Carlos; Dimiccoli, Mariella (2019)
    Conference report
    Open Access
    Our interaction with the world is an inherently multi-modal experience. However, the understanding of human-to-object interactions has historically been addressed focusing on a single modality. In particular, a limited ...
  • Unsupervised image-to-video clothing transfer 

    Pumarola Peris, Albert; Goswami, Vedanuj; Vicente, Francisco; De La Torre, Fernando; Moreno-Noguer, Francesc (2019)
    Conference report
    Open Access
    We present a system to photo-realistically transfer the clothing of a person in a reference image into another person in an unconstrained image or video. Our architecture is based on a GAN equipped with a physical memory ...
